Off hand I'd say that carbon film, metal or wire wound will work just fine in this application. About wattage, if it's about 3/8 to 1/2 long and perhaps 1/8" in dia, use a 1/4 or 1/2 Watt resistor...

The original looks like a carbon composition, but can i use a carbon film, metal or wire wound? Any idea on the wattage of the original?

I tested 40v across the terminals so the wiring is working. Pulled out the gauge, and opened it up. Blown resistor. Anybody know what the proper replacement is? Seems to be a carbon composition resistor with orange-black-red-gold bands. I used an online identification tool and it tells me it is a 3000 ohm +/- 5%.
